Corresponding measures are necessary for protection of constructions and DC power supply systems networks against corrosion caused by stray parasitic currents.
PLUTON stray currents monitoring system is simple and efficient method of stray currents monitoring and traction power supply system long lifetime provision.
Stray parasitic currents are leak currents, which are defined as currents deviating from their supposed paths.
Influence of stray current on infrastructure:
fast rails metal corrosion;
piping metal damage and pitting corrosion;
corrosion of concrete frames reinforcing bar near the line;
macro and micro cracks in concrete;
cable armoring (enclosure) corrosion damage.
Operation principle and functions of the stray currents monitoring system
principle is based on potential measurement with stray currents monitoring system;
continuous track rails potential monitoring during operation;
potential values displaying and archiving in central station;
analysis and automatic detection of sections with damaged insulation;
data access in real time mode via SCADA;
regulating standard — EN 50122-2/IEC 62128-2.
Running rail section should be certified according to insulation standards requirements before SCMS implementation and potential measurement.
